Control cables not spreading combustion KVVGEzng(A)

CONSTRUCTION
1. conductive core - single-wire round, 1 class according to GOST 22483 made of soft copper (nominal cross-section from 0,75 to 6,00 mm2) wire.
2. insulation of cores is made of polyvinylchloride plasticate.
3. Core - insulated cable cores twisted by twisting.
4. Separating layer (sheath) - made of polyvinylchloride plastic of reduced flammability with filling the gaps between the cores.
5. shield - in the form of aluminium foil wrapping with overlapping, providing the screen continuity at permissible bending radii of cables. A tinned copper wire is laid longitudinally under the screen.
6. The sheath is made of polyvinylchloride plasticate of reduced flammability.
Cables are designed for transmission and distribution of electrical energy and electrical signals in stationary electrical installations that require cable sealing at entry, at alternating voltage up to 660 V with frequency up to 100 Hz or direct voltage up to 1000 V.
